What The Most Realistic Streaming Audio On The Internet Can Do For You.
audio is digitized audio that's been compressed or encoded into a format that
a server can break down into packets and then broadcast (or stream) across
a network to a client player. The player then reassembles the data packets
in the correct order and plays back the audio. All in real time, without frustrating
download delays. Streaming audio works very much like a CD player. Once the
download starts, the player buffers (or temporarily stores some of) the incoming
data to provide smooth playback, then begins playing while the file continues
RealAudio System delivers the highest-quality audio, from basic speech to full
symphonic music, at all bandwidths on the Internet. And it was the first system
to deliver stereo sound at 28.8 kbps, as well as near-CD quality at ISDN and
LAN connection speeds. This - combined with reliable transmission of data,
the ability to scale streams to thousands of users, and multiple delivery options
including UDP, TCP and HTTP - is why the RealAudio System is the market leader
in audio on the Internet today. Superior technology. That's why more than 15
million copies of RealAudio have been distributed worldwide, with tens of thousands
of new downloads every day.
